You know, my boy, he said, it's impossible to love men such as they are. And yet we must. So try to do good to men by doing violence to your feelings, holding your nose, and shutting your eyes, especially shutting your eyes. Endure their villainy without anger, as much as possible; try to remember that you're a man too. For, if you're even a little above average intelligence, you'll have the propensity to judge people severely. Men are vile by nature and they'd rather love out of fear. Don't give in to such love: despise it always.

If everything on earth were rational, nothing would happen.

There is no explaining anything by reasoning and so it is useless to reason.

The man who lies to himself can be more easily offended than anyone else. You know it is sometimes very pleasant to take offense, isn't it? A man may know that nobody has insulted him, but that he has invented the insult for himself, has lied and exaggerated to make it picturesque, has caught at a word and made a mountain out of a molehill--he knows that himself, yet he will be the first to take offense, and will revel in his resentment till he feels great pleasure in it.

Where is it I've read that someone condemned to death says or thinks, an hour before his death, that if he had to live on some high rock, on such a narrow ledge that he'd only room to stand, and the ocean, everlasting darkness, everlasting solitude, everlasting tempest around him, if he had to remain standing on a square yard of space all his life, a thousand years, eternity, it were better to live so than to die at once. Only to live, to live and live! Life, whatever it may be!

A beast can never be as cruel as a human being, so artistically, so picturesquely cruel.

Two and two make four. Nature doesn't ask your advice. She isn't interested in your preferences or whether or not you approve of her laws. You must accept nature as she is with all the consequences that that implies.
